Answer 1

Point topCenterPoint = new Point(this.pictureBox1.Width / 2, 0);

//测试代码
Graphics g = pictureBox1.CreateGraphics();
g.Clear(Color.White);

g.SmoothingMode = SmoothingMode.AntiAlias;

g.CompositingQuality = CompositingQuality.HighQuality;

Point bottomCenterPoint = new Point(this.pictureBox1.Width / 2, this.pictureBox1.Height);

g.DrawLine(Pens.Red, topCenterPoint, bottomCenterPoint);
